In anapplication for 1' UnitedS t ates Letters 5 .Patent, Serial N0.:.537, 635, filedfMay 15, 1931; Of

.which the present application isfa' division; there .is described a heel the central portion of the breast of which is providedwith' three parallel slots located adjacent toeach other-land extending heightwise of the the forward projecting portions ofthe side cover are inturnedupon the lateral portions of .the .breastof the heeLthema'rgins of such portions being tucked into the outer two ;slots, res pectively. A separatepanel strip is-'laid;upon the .por-

tion of the heel 7 breast included-between the two outer slots and has its lateral margins tucked into the outer slots-alongside the tucked in margins of the side-cover, Thinribs- ;are forrned;between-the central slot andthe two outer-slots, the sr s ead y fl x d .-.t e .ic er ma iginsare tucked into the slots thereby to expand theslots to expedite the covering; operation.

After the side cover and the panel strip have been appliedto the heel a filler: piece is slid in the centerslot to insure that thesmargins of :the cover and: the strip. are securely 'held within the router slots; Y

The means for pressing and smoothing the margins of the side cover against the breast of the heel includes rolls which'are positioned along the outside faces of the blades. The tool for tucking the panel strip into the outside slots is provided and pointed out in the app nded claims,

Fig. '6 s; .a. perspective view 'illustratingbeen laid upon the heel breast 26 are next trimmed simultaneously to the proper width by moving a hand knife 32.,(Fig. 1) guided along the center slot 24 against overlapping forwardly projecting portions 30 of the side cover,'and the respective margins of the projecting portions 30 are then tuckedinto the outer slots 22. In order to cover the portion of the breast 26 of the heel included between the outer slots 22 a panel strip 34 is laid 3:5 the tucking operation to increase the width of the slot into which the margins are inserted. A

upon such portion,

margins.

the lateral margins of which strip are tucked into the slots 22 alongside the tucked-in margins of the side cover 28. It will be understood that the heel and the inside face of the sidecover 28 are usually coated with rubber cement prior to the heel-covering operation.

By providingthe center slot 24 the t ucking of the margins of the forwardly projecting portions 30 of the side cover and the panel strip 34 into the outer slots 22, respectively, is facilitated since ribs or walls 36 (Fig. 3) which are included between the outer slots 22 and the inner slot 24 are temporarily bent under pressure of a. tucking tool '38, the construction of which will later be described,

thereby to widen the slot 22 and to'permit entry of themargins of the cover and the tool. "The ribs 36 spring back into their normal positions illus-' trated in Fig. 8 after the tucking tool has been removed, and effectively clamp thetucked-in In order to fill up the center slot 24 after the heel has beencovered and to insure that the tucked-in margins are positively clamped within theouter slots 22, a filler piece 40 (Figs. 5

and 8) is insertedin the center slot 24. The f "and'10 the tucking blades and the rolls of the panel strip 34 may be of a different color than the side cover 28 and this gives the heel an attractive appearance.

iFigs. 9and disclose a slightly modified heel 42 providedwith apanelstrip 44 extending over asubstantial width of the breast of the heel. The" wide panel strip 44Vhas its lateral margins tucked into outer slots 46 alongside the tucked-in margins lof'ithe side cover.

In order to expand the outer slots 46 a pair of inner slots 48 are'formed to provide ribs or walls 50 which may be flexedduring filler piece 52 similar to the -filler piece 40 maybe inserted withineachof the inner slots 48 when the margins of the side cover and the panel strip 44 have been, securely tucked into thejouter slots In order quickly and effectively to tuck the margins of' the'side cover 28 into the outer slots 22 a rotary tool 54 (Fig. 2) is provided. The tool 54 may berrotated under pressure and translatory movement of the heel or may be'positively rotated at a slow-rate of speed. The tool 54 com-' prises aflpair of spaced disk-likej tucking blades 56 and a pair'of rolls 58 positioned adjacent to the outside faces of the blades .56 and constructed and arranged to lay the margins of the side cover 'againstportion's of the breast which are located adjacent to the'slots 22, respectively. ,Thewidthwise curvature of the work-engaging faces of the rolls 58 is substantially complemental to the transverse curvature of the breast of the heel. a I

The .marginsof the panel strip 34inay be tucked intothe slot's'22 alongside the tucked-in.

margins 'of the side cover by the above-mentioned rotary tool 38 which comprises a pair of spaced disk-like tucking blades 60 andia strip-applying roll 62 interposed-between the blades and constructedand arranged to force the panel strip 34 against the portion of the breast of the heel included between the outer slots 22 as the margins of the strip 34 are tucked into the slots. The

rolls 58 of the tool 54 and the roll 62 of the tool 38 are preferably made of rubber or like material. In order to facilitate the tucking of the margins of the panel strip 34 into the outer slots 22, respectively, the portions of the blade 60 which I a portion of the heel breast included between the slots 22fbeing laid upon the heel and the heel then being forced against and moved past the tool 38 to tuck the margins ofthe strip into the respective slots. The panel strip 34 is then trimmed to the proper length by a pair of scissors 66, asillustrated in Fig; 6. v v V V Y In covering the heel 42 villustrated in Figs. 9

tools 38,154 are constructed and arranged in accordance with the position of the heel-cover receiving slots 22. k g l Having described the invention, what I claim as new and desire to secure by Letters Patent of the United States is:

- 1. A tool for applying covers'to heels'comprising means for progressively laying a strip of covering material upon a heel surface between parallel slots said surface, and means for progressively tucking fthe lateral marginsof the strip into such slots'as the strip is being laid.

'2. A- tool for use in applying covers to heels 'comprising.a-roll for laying a strip of covering "material upon a heel-surface between parallel slots therein, a'nd'two-disks arranged one at each side of-th'e'roll for simultaneously tucking the lateral margins of the strip into said slots as the strip isbeinglaid.-

3. A rotary tool for use inapplying heel covers comprising arch of yielding material forlaying a cover strip upon a heel surface between parallel slots therein, and two, disk-like members arranged one at each end .of the roll for simultaneously tucking thelateral margins of thestrip into said slots. .2 1 l 4'. A rotatable tool for'use, in applying covers to heelscomprisin'g a roll forlaying a strip of covering materialupon a portion of a heel surface located between parallel cover-receiving slots between whichis included. a third slot spaced from the cover-receiving-slotsrespectively by ribs, and two disks arrangedat opposite sides of the roll forsimultaneously tucking the lateral'rnargins of the strip into said cover-receiving 'slots as the strip is being laid, opposing work-engagin faces of the disks being in converging relationto bend the ribs toward each other as the disks enter the cover'-receivingslots. v i y
